HTTF Integral Model
The Hedland HTTF Ultrasonic Transit Time Flow Meters clamp onto the outside of existing piping and do not contact the internal liquid. This advanced product provides instantaneous rate and accumulated flows along with 4-20 mA and pulse outputs. These non-invasive, compact meters were designed to replace mechanical flow meters in applications where liquid conditions tend to damage or impede mechanical flow meter operation.
Features Include:
- Non-invasive meter clamps onto the outside of existing piping
- Easy, low cost installation
- No moving parts for maintenance free operation
- Pipe sizes 1/2 inch through 2 inches
- for larger pipe sizes see the HTTF Remote Model
- Available with or without a local display
- Direct interface to data collection systems
- Bi-directional flow capability to measure forward total, reverse total and net total
- ULTRALINK™ Windows®-based software utility allows configuration, calibration and troubleshooting
Typical Applications:
- Chemical distribution
- Machine tool/process cooling
- Well water
- Remediation
